Title: Magnetic recording medium as well as substrate for forming magnetic recording medium and magnetic disk device
Inventor: SHODA MITSUHIRO
IPC: G11B5/73
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To permit sliding reliability and low sticking characteristic without impairing low floatability by having impact buffer regions where recording and reproducing are not executed between CSS regions and data regions and having projections having an average projection density higher than the average density of the projections formed in the CSS regions in these impact buffer regions.

The projections are formed in the CSS regions 102 and the impact buffer regions 103 on the substrate after washing by laser processing. The impact buffer regions 103 are formed at the intermediate between the CSS regions 102 and the data regions 104, and the CSS regions 102 respectively have the projection shapes, by which both of initial stiction and CSS friction force may be suppressed to a lower level and the abrasion wear of the projections may be suppressed as well.

Filed: 1985-06-27
Abstract: PURPOSE:To prevent waveguide mode excitation through eliminating the possibility of useless resonace mode excitation by a method wherein a recess is provided approximately 1/4 wavelength apart from a side wall of a metal block and the sidfe wall involving the recess is allowed to make a non-contact access to a high frequency shield case. CONSTITUTION:A microwave circuit is constituted of signal lines 2 arranged on one surface of a microstrip substrate 1 fixed secure to a metal case 4 together with a metal block 8 by means of a flush head screw 6 and round head screw 7. The case 4 and a metal cover 5 constitute a high-frequency shield case. The metal block 8 is shaped after an inverted letter L, provided with a recess in a side wall C facing a side wall A, and the distance between the side wall A and the recess, that is, the distance (b+c) that is the sum of the lengths (b) and (c) respectively of the side walls B and C, is approximately equal to 1/4 of the frequency whereat the microwave circuit operates. This results in an equivalent short circuit between the side wall A and cover 5. This in turn results in an equivalent reduction in the inner width of the case 4, which contributes to the prevention of waveguide mode excitation.

Title: Temperature controlling sheet set and method for using the same
Inventor: IIDA TAKESHI
IPC: G01K11/12
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To detect simply the presence of goods and custody places held in a temperature below a predetermined one by applying a sensible heat recording sheet and an adhesive sheet through a first adhesive layer onto the surface of a sensible heat recording layer when in use. SOLUTION: A temperature controlling sheet set can control the preservation temperature for goods or custody places by applying an adhesive sheet through a first adhesive layer onto the sensible heat recording layer of a sensible heat recording sheet. A discharging temperature and time can be controlled by selecting basic dye, coloring agent, discharging agent and the like to be used. For example, after bar codes are recorded on the sensible heat recording sheet by a label printer, the adhesive sheet is applied. While the sensible heat recording sheet is left below a predetermined temperature, the bar code record is not discharged. However, when the predetermined temperature is exceeded, the bar code record is gradually discharged.  About 25-250μm thick paper, film, synthetic paper, laminate paper and the like may be used for a support of the sensible heat recording sheet and adhesive sheet.

Abstract: PURPOSE:To ensure the sending of a digital service channel signal by sending a digital service channel signal and a signal detecting the state of a line fault at a radio terminal station reception section without error from an intermediate repeater station if line interruption due to a fault of the intermediate repeater station takes place. CONSTITUTION:A frame synchronization signal generation section 2 generates a frame synchronizing signal and a pseudo random signal generating section 3 generates a pseudo random signal respectively in place of a main signal by using an output of an oscillator 1 according to a timing control signal from a timing control signal generating section 5.

A multiplex section 6 multiplaxes a frame synchronizing signal and a pseudo random signal, and the parity bit and the pseudo random signal, and sends them together with the pseudo random signal and a digital service channel (DSC) location signal. Thus, while the sending of the DSC signal is ensured in case of the line fault, the line relieve is started.
